This example tests the SWIG run-time libraries and use of the
%import directive to work with multiple modules.
Use 'ruby runme.rb' to run a test.
Overview:
---------
The example defines 4 different extension modules--each wrapping
a separate C++ class.
base.i - Base class
foo.i - Foo class derived from Base
bar.i - Bar class derived from Base
spam.i - Spam class derived from Bar
Each module used %import to refer to another module. For
example, the 'foo.i' module uses '%import base.i' to get
definitions for its base class.
If everything is working correctly, all of the modules will load
correctly and type checking will work correctly. The
example requires the use of the SWIG run-time libraries
which must be built and properly installed.
